11 / 23 page —11— CXA3235/3236N Description of PLL Block The PLL on this IC supports the I2C bus control format. The control pins are as shown in the table below. 1) Mode Setting Method The modes for each frequency step are set according to the MS pin voltage. Symbol ADSW SCL SDA Description Address selection SCL input SDA I/O Mode B-0 B-1 B-2 B-3 B-4 MS pin voltage 0 to 0.15 VCC OPEN 0.45 VCC to 0.55 VCC 0.65 VCC to 0.75 VCC 0.85 VCC to VCC Main divider 15 bit 14 bit 15 bit 15 bit 15 bit Reference divider 1024 512 640 512 512/ 640/ 1024 Reference frequency 3.90625 kHz 7.8125 kHz 6.25 kHz 7.8125 kHz 7.8125 kHz/ 6.25 kHz/ 3.90625 kHz Frequency step∗ 31.25 kHz 62.5 kHz 50 kHz 62.5 kHz 62.5 kHz/ 50 kHz/ 31.25 kHz ∗ Frequency step is for when X’tal OSC = 4 MHz. 2) Address Setting The responding address can be changed according to the ADSW pin voltage, so that multiple PLL can exist within one system.
